A plication filed February 28, 1905. Serial No. 247,799.

To all whom it may concern:

Be it known that I, EUGENE lVIn'r, a citizen of the United States,residing at Sacramento, in the county of Sacramento and State of Cali-Hook, of which the following is a specification.

This invention relates particularly to improvements 1n haine-hooks, butis not limited The principal object is to provide a novel and simplehook in which a link or other connector is securely locked againstaccidental detachment, the structure of said hook being such that it canbe formed of sheet metal stamped or punched by ordinary mechanism, thusmaking it very inexpensive to manufacture, and, while constituting anefficient lock, being readily operable to release the link or otherdevice held thereby.

The preferred embodiment of the invention is illustrated in theaccompanying drawings, wherein Figure 1 is a side elevation of theimproved hook. Fig. 2 is a cross-sectional view taken on the line 2 2 ofFig. 1. Fig. 3 is a detail perspective view of the hook-body. Fig. i isa similar view of the locking device, and Fig. 5 is a detail sectionalview on the line 5 5 of Fig. 3.

Similar reference-n umerals designate corresponding parts in all thefigures of the drawings.

ln-the embodiment illustrated a hook-body 6 is employed, which is formedof a sheet-metal blank or plate having a front and rear end, the rearend being turned to form an eye 8. A. slot extends into the plate fromone of its side edges, preferably the upper edge, and thencelongitudinally of said plate toward the front end 7 thereof, forming ashank 7, an overhanging bill 9, an article-receiving seat 10, and anentrance-mouth 11, the free terminal of the bill being furthermoreprovided with an inwardly or downwardly extending nib 12. The end wallof the seat 10 is preferably thickened by upsetting the metal, as shownat 13, in order to provide an extended wearing-surface.

Pivoted upon one side of the shank in rear of the entrance-mouth 11,, bymeans of a suitable rivet 14, is a locking device that is preferably,though not necessarily, in the form of a disk 15. The reason forpreferring the device to be in the shape of a disk is that it may bereadily made by a circular punch. The rivet 14 passes through thelocking device eccentrically thereof, but substantially midway betweenits side edges, and is located in rear of the entrance-mouth 11, asfully shown in Fig. 1. Therefore the disk will under ordinary conditionsassume a position across said mouth, consequently closing the same andthe article-receiving seat, said disk swinging to this position whenmoving rearwardly' toward the rear end of the plate. In order tolimitthis rearward movement of the locking device and prevent theuncovering of the entrance-mouth 11, a stop-stud 16 may be employed, ifdesired, which stud, as shown in Fig. 5, may be struck from the metal ofthe shank and is located in rear of and in the path of movement of thelower rear edge of the locking device, which edge strikes the stud uponthe rearward edgewise movement of the disk while said disk is across theentrance-mouth. This is also fully illustrated in Fig. 1.

In order that the locking device may be readily operated by a teamsteror other person, it is provided with a projection 17, struck outwardlyfrom the same, and thereby forming a recess or socket 18 in the innerside. This recess is arranged. to detachably receive a projection 19,formed upon the adjacent face of the shank, as shown in Figs. 2 and 3.The projection fitting in the socket when the looking device is inoperative position across the mouth holds said device against play andagainst accidental movement to an inoperative position, yet whenpressure is applied to said device by an operator the locking devicewill pass over the projection 19 on the shank and can thus be swungaround to open the mouth and permit therelease of a link, as 20, orother article held in the hook.

From the above it will be clear that the complete hook, including thelocking device, may be readily constructed of sheet metal by mechanismwell known in the arts, that the same can be inexpensively manufactured,and, while constituting an efficient lock-hook, can be readily operated.

From the fo'reging it is thought that the construction, operation, andmany advantages of the herein-described invention will be clear to thoseskilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to Without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, What Iclaim as new, and desire tosecure by Letters Patent, is

1. In a lockhook,a body stamped from sheet metal and comprising a platehaving a front and rear end, a slot extending in from its upper edge andtoward the front end, forming an upper overhanging bill, anarticle-receiving seat and an entrance-mouth, a locking device stampedfrom sheet metal and pivoted substantially midway between its front andrear edges and contiguous to its upper end upon one side of the body inrear of the entrance-mouth and directly adjacent to the upper edge ofthe body, said device having an edgewise-swinging movement toward therear 7 end of the plate and across the mouth to close the same, andmeans stamped from the sheet metal of said body and located in rear ofthe locking device and in the path of movement of its lower rear edgefor stopping the device when said device is across the mouth andpreventing its rearward movement to uncover the mouth.

2. In a lockhook,a body stamped from sheet metal and comprising a platehavinga front and rear end and a slot extending in from one edge towardthe front end of the plate, forming an article-receiving seat and anentrancemouth, a locking-disk stamped from sheet metal and eccentricallypivoted at one side of its center upon one side of the plate in rear ofthe entrance-mouth, the larger portion of said disk on one side of thepivot having an edgewise-swinging movement toward the rear end of theplate and across the mouth to close said mouth, and a stop carried bythe body and disposed in rear of and in the path of movement of saidlarger portion of the disk to prevent the edgewise movement of said diskrear- Wardly away from the entrance-mouth.

3. In a lock-hook,a body stamped from sheet metal and com prising aplate, said plate having a slot extending in from one edge toward oneend of the plate, forming an article-receiving seat and anentrance-mouth, a locking-disk stamped from sheet metal and pivoted atone side of its center between the entrance-mouth and the eye. thelarger portion of said disk on one side of the pivot swinging across themouth to close the same, an outstanding integral lug stamped from thebody and located in the path of movement of one edge of the disk toprohibit the edgewise movement of said disk in one direction away fromthe mouth, and projections struck outwardly upon the disk and body atone side of the slot, the projection of one interlitting in thecorresponding recess of the other when the disk is against the lug.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two Witnesses.

EUGENE IVIET.
